The Kuiper Belt is made up of millions of icy and rocky objects that orbit our sun beyond the orbits of Neptune and Pluto. Astronomers think some comets come from the Kuiper Belt. Most dwarf planets are in the Kuiper Belt.
It's hard to say exactly what's going on in the Kuiper Belt. Even the biggest of the Kuipet Belt Objects is smaller than the United States of America. They also are billions of miles away where the sun's light is weak. They are very hard to see even with the most powerful telescopes.
Kuiper Belt Objects are so hard to find that it took more than 40 years to find one after a scientist worked out the math that said they should be floating around way out there on the edge of our solar system.
